Today there is a new update to Flash Professional CC (13.0.1). You can receive these updates through the creative cloud desktop application. I have not tried to get the updates through the update in the Flash IDE, but I am sure that will work as well.
Some of the new bug fixes in this update
Flash Professional CC 13.0.1 Update contains important bugs fixes. The following is a list of all bugs fixed in this update:
[Reference #3590263]: The Welcome Screen fails to load on launching Flash CC. And also, Flash CC crashes on creating a document, if FlashFirebug add-on is enabled for Mozilla Firefox. Due to this, the Test Movie window does not load.
